ETUDES LEPIDOPTE'ROLOGIE COMPAREE. By CHARLES OBERTHUR. Volume 

 IX, Part I. 



This part contains an exceedingly important contribution to Ameri- 

 can Lepidopterology, as herein Mr. Oberthiir gives 74 figures in color, 

 of the species of Californian butterflies, described by Dr. Boisduval in 

 the Annals of the Entomological Society of France in 1852 and in the 

 Annals of the Entomological Society of Belgium in 1869. Dr. Boisdu- 

 val's descriptions were often brief and he compared the Californian 

 species with those of Europe in a very few words. It has been quite 

 difficult, on account of the variation in the species of Californian Ly- 

 caenidae and Hesperidae, to be certain about some of Dr. Boisduval's 

 species in reference to those described by Dr. Herman Behr, \\ilham 

 H. Edwards, Henry Edwards and others. By means of these beauti- 

 ful and accurate figures given by Mr. Oberthiir it will be possible to 

 put the study of the Californian diurnal Lepidoptera on a firm founda- 

 tion. American students of these insects owe a great debt of grati- 

 tude to Mr. Oberthiir for so generously supplying figures of these 

 types and recognizing the necessities of the case. 



It may prove useful at this time to make some comments on the spe- 

 cies in relation to their validity or synonymy. 



Theda borus Bd. is a synonym of calif ornica Edw. 



Thecla auretorum Bd. The da spadix H. Edw. is a synonym of this. 



Thecla sylvinus Bd. This species I do not know, unless it is a race 

 or variety of calif ornica Edw. 



T. iroides Bd. is a synonym of augustus Kirby. 



Thecla gryphon Bd. is a western race of niphon Hiibn. 



Thecla dumetorum is a synonym of rubi Linn. 



Chrysophanus arota Bd. The species described as virginiensis by 

 Edwards is close but apparently sufficiently distinct for specific rank. 



Chrysophanus xanthoides Bd. Dione Scud, is close to this. 



Chrysophanus nivalis Bd. This has erroneously been put into the 

 synonymy in our lists under mariposa. 



Chrysophanns zeroe Bd. is a synonym of mariposa Reak. 



Lycacna suasa Bd. is a synonym of fuliginosa Edw. 



Lycacna antiacis Bd. This must be a rare form. Polyphemus Bd. 

 is the common species in California. 



L. rhaea Bd. is a synonym of sagitiggera Feld. 



L. nestos Bd. is a synonym of podarce Felder
